Title: Manufacture of josephson junction element
Inventor: TSUGE HISANAO
IPC: H01L39/24
Filed: 1984-09-11
Abstract: PURPOSE:To obtain the high-quality junction without producing contamination in a tunnel barrier layer by forming the first superconductive electrode, a tunnel barrier layer, and the second superconductive electrode continuously by use of Josephson junctions of Nb group, oxide, and Pb group. CONSTITUTION:The first superconductive electrode 12 consisting of Nb or Nb compound is vapor deposited on an insulating substrate 11 and the surface is subjected to thermal oxidation or plasma oxidation to produce a tunnel barrier layer 13 on a surface of the electrode 12. Next on that, the second superconductive electrode 14 consisting of Pb or Pb alloy is formed by the similar method and a resist mask 15 is arranged on a tunnel barrier part present on said electrode 14. By ion etching using a mixed gas of Ar and O2, an exposed part of the electrode 14 and subsequently the barrier layer 13 under that are removed. Thus by the ion etching using a mixed gas of Ar and O2 having a good selective ability and anisotropy, the tunnel barrier part of a high accuracy in size in which overetching is negligible can be obtained.

Title: Air conditioner for motorcar
Inventor: FUKUSHIMA TOSHIHIKO
IPC: F25B1/00
Filed: 1982-10-29
Abstract: PURPOSE:To improve the fuel consumption efficiency without deteriorating the capacity of room cooling by a method wherein the device is designed so as to keep a value, obtained by dividing the stoke volume of a compressor with a pulley ratio that means the ratio between the diameter of the crank pulley of an engine and the same of the pulley for the compressor, within the value of 90-140. CONSTITUTION:In case the capacities of the compressor 1, a condenser 7, an evaporator 9 and the like are improved, the room cooling capacity is inceased also compared with the former air conditioner in which the capacities of them are not improved, therefore, the fuel consumption of the engine 2 may be reduced if the pulley ratio is increased so as to bring the room cooling capacity into the same degree of the air conditioner before improving the capacities thereof. Here, the pulley ratio (stoke volume/pulley ratio) is designed with respect to the stoke volume of the compressor so as to become within the value of higher than 90 and lower than 140. According to this method, the effect of the improvement of the fuel consumption may be enlarged without causing the shortage of cooling capacity.

Title: Arm controller
Inventor: OOTANI AKIHITO
IPC: G11B3/095
Filed: 1983-10-07
Abstract: PURPOSE:To always fix the falling position of a tone arm by using a photointerrupter to detect the light transmitting through a slit plate and detecting the edge position of a record disk having different diameters at edge parts of two rows of slits. CONSTITUTION:A slit plate 2 is attached to a tone arm 1 and changes its position in the moving direction of the arm 1, and two rows of slits 8 are provided on the same circumference of the plate 2. The light is detected when a photointerrupter 4 reaches a falling position E of a 30cm-record disk. Then the arm 1 is stopped and moved down by a control circuit 6. A 17cm-record disk falls at a position F. Therefore just a single unit of the interrupter 4 suffices and the position control of the interrupter 4 is simplified. In addition, the position shift is eliminated for the arm 1 since the falling position of the arm 1 is detected only with the light rise. Thus the arm 1 is always set at a fixed position of a record disk.

Abstract: PURPOSE:To extend a field of view without influencing seating feeling by installing a cushion seat in a fixed frame via a link mechanism so that the front end part of the cushion seat, whose rear end part is installed freely adjustably in the vertical direction, dose not move downward but moves backward when the rear end part is shifted upward. CONSTITUTION:When an operation dial is operated and a rear side rotating arm 11 is rotated by a sector gear 24 and a rod 22 via a gear 26, a pivot part 13 is moved upward against a pivot part 18, so that a rear part of a cushion seat 2 is greatly lifted. According to the upward movement of the tip (the pivot part 13) of the rear side rotating arm 11, a side frame 7 is moved, so that part 10 is moved and a front side slanting rotating arm 9 is rotated. As the front side slanting rotating arm 9 is arranged slantingly, rotating width in the vertical direction is narrow and the front end part of the cushion seat 2 is not moved vertically. On the other hand, the longitudinal moving distance is long, so that the tip (the part 10) of the front side slanting rotating arm 9 is rotated toward the back side.

Abstract: PURPOSE:To restrain a temperature difference in the surface of a substrate in an uniformly heating section to a minimum value and prevent the generation of defects such as the damage or faulty soldering of a part and the like by providing a forced convection type heating means in the uniformly heating zone. CONSTITUTION:A temperature rise-up section consisting of an infrared ray heater 22, an uniformly heating section consisting of a hot air forced convection means 23 and the infrared ray heater 24 and a main heating section consisting of the infrared ray heater 25 are arranged sequentially in series in a re-flow furnace 31. A substrate 7, transferred into the re-flow furnace 31, passes through the temperature rise-up section and, thereafter, is heated by the radiation heat of the heater 24 and the convection of hot air in the uniformly heating section. According to this method, the surface of the substrate, which is provided with a small heat capacity, is restrained in temperature rise due to the radiation heating while the temperature of a part having a large heat capacity is risen by the synergistic effect of the radiation heat and the convection whereby a temperature difference in the whole of the substrate becomes small. Accordingly, the generation of defects may be prevented.
